Checks whether * this is non-null, i.e. the value of * this is obtained from the promise object of some coroutine. Equivalent to return bool ( address ( ) ) ; .
If
Promise
is
std::noop_coroutine_promise
, this conversion function always returns
true
.
Parameters
(none)
Return value
bool
(
address
(
)
)
, or
true
if
Promise
is
std::noop_coroutine_promise
.
